Prevent Screen Capture with DirectX

I want to make a single image using DirectX. It should work like a directx video output VLC player if it is not possible to capture a frame using simple screen capture software or a print screen key. It is impossible (or very difficult) to take a screenshot!

Does anyone know how this works in a VLC player?

Are there any other possible solutions? Perhaps with "Output Protection Manager" (see http://msdn.microsoft.com/en-us/library/dd388980(VS.85).aspx )

I have about 3 years of C # programming experience at school. I also did some C ++ programming, but I would rather use a C # solution using WPF or Managed DirectX.

Sorry for my English and thanks for your help in advance.
